STOP MEcHAN-lslvl Fon CARDINGY-MACHINES.

srncfrrcArroNfforming part of Letters Patent No. 559,160, dated April 28, 189e.

Application filed May 23,1895.r Serial No. 550,322. (No model.)

To all 2071/011?, it may concern:

Be it known that we`,DAvID F. BRADBUR and GEORGE McDEEMorr, citizens of the United States, residing in the Vcity and county of Philadelphia, State of Pennsylvania, have, invented a new and useful Improvement in` Stop Mechanisms for Carding-lvlachines,&c. ,5 which improvement is fully set forth in the, following specification and accompanying drawings. 4 Our invention relates to cardingmachinesg and it consists of a novel construction of au-` tomatic stop 4attachment therefor, by means of which the rotation of the feed-rolls will be instantly stopped in case any'obstructionl is encountered between the licher-in roll and its adjacent roll, the parts being readily thrown into operative position again as soon as said obstruction has been removed.

It further consistsof novel details of construction, all as will be hereinafter set forth. Figure 1 represents a side elevationv of parts of a carding-machine and an automatic stop attachment therefor embodying our invention. Fig. 2 represents a plan view of the same on an enlarged scale, the right-hand end of the machine seen in Fig. 1 being broken away. Fig.` 3 represents a partial front elevation of the machine, showing the feed-rolls and the tripping mechanism for stopping the: same, said tripping mechanism having been just operated. Fig. `4 represents a perspective view showing the tripping mechanism in operative position, the same being just about to be actuated. Fig. 5 represents a partial sectionalvicw through a portion of the automatic stop attachment.v Fig. 6 representsa section on line al, Fig. 1.

l Similar numerals of reference indicate cor-` responding parts in the several figures.

Referring to the drawings, 1 designates the frame of a carding-machine, having mounted in suitable bearings near an end thereof the feed-rolls 2 and 3, the shaft 4 of one of said feed-rolls being extended through its bearings on the frame and having mounted thereon the gear 5, which meshes with the pinion 6, which latter is attached to thel bevelgear S, so as to move in unison therewith, said pinion and bevel-gear being rotatably mounted on a sui table stud 7. 9 designates anotherbevel-gear, adapted to be in mesh with said gear 8 when the parts are in their normal position, said gear 9 being mounted upon the shaft 10, which has a bearing in the disk 11, said bearing being eccentrically located within said disk, while the latter has its bearing in a sleeve or ring `12, said shaft 10 having an eccentric bearing also in the disk 13, which is attached to said disk 11, said shaft 10 being freely movable in said disk 13, While the latter has attached thereto the stem or handle 14, which has projecting therefrom, at an an gle,the pin 16, said stem 14 having attached thereto one end of a spring 17, the other end of the latter being attached at 18 to any suitable fixed point, as the bed 1.

19 designates a stationary bearing for shaft 10, which latter` has mounted thereon the bevel-gear 20, which meshes with the bevelgear 21, the same being attached to the gear 22, soas to revolve in unison therewith, said gears 21 and 22 being rotatably mounted upon a suitable stud 23. 24 designates a pinion in mesh with said gear 22 and rotatable on a stud 25, which isV attached to a suitable portion of the frame 1, said pinion 24 being in mesh with `a pinion 26, which is mounted on the shaft 27 of the doffer-roll 28, said shaft 27 having mounted thereon a pulley 29, (seen dotted in Fig. 1,) around which passes a belt 30, which is crossed in the present instance and engages a pulley (seen dotted in Fig. 1) on the shaft 32, upon which latteris mounted the main cylinder 31.

rIfhe shaft 32 has secured thereto a pulley 33, around which passes a belt 34, which is crossed in the present instance and is adapted to transmit motion to the pulley 35, which is mounted upon the shaft 35 of the tumbler 36.

37 designates a pulley mounted upon the farther end of the shaft 32, around which passes a'straight beltV 38, said pulley and belt being broken away in Fig. 2, and said belt 33 engaging the pulley 39 on the'farther end of 95 the licher-in roller 40, whichlatter rotates with the shaft 40X. 41 designates a traveler which is freely mounted on the end of said shaft 40X, as will be explained, said traveler having a `belt 43, passiugaround the same,

IOO

and the pulley 44, mounted upon the shaft o2, to which lat-ter shaft power is to be applied in the first instance.

44 designates an arm which is attached to the frame 1 and projects therefrom, as will be understood from Figs. 2 and 3, said arm having attached thereto the boss 45, on which is pivotally mounted the dog 46, which has one end 47 thereof bent at an angle thereto, the other end of said dog being provided with a notch or recess 48, which is adapted to engage the pin 16 when all the parts are in operative position, asis best seen in Fig. 4. Projecting from the outer face of the traveler 41 is a pin 42, adapted to contact with one end of said dog 46, for a purpose hereinafter explained. 49 designates a pin or stud, which is attached to the interior of said traveler 41 and has its projecting end adapted to engage a worm 50, which revolves with the shaft X, which carries the licher-in roller 40, said worm being left-handed in the present instance and terminating at each end in an annular groove 51 and 52, as will be understood from Fig. 2, it being apparent that when the traveler 41 is rotating in its proper direction, as indicated by the arrow in Fig. 4, the edge 41X of said traveler will be nearly in alinement with the outer wall of said worm 50.

The operation is as follows: Power having been applied to the shaft 32, and the different rollers and gears being revolved in the directions indicated by their respective arrows, it will be evident that the face 41 of the traveler 41 will be normally in the position seen dotted in Fig. 2, the licher-in roll 40, the feedrolls 2 and 3, and the other rolls revolving in unison, as will be understood by following out the train of gearing and belting. If now any obstruction 53 becomes interposed between the licher-in roll 40 and the adjacent feed-roll 2 of such character as to stop the rotation of said licher-in roll, the rotation of the worm will cease, but by reason of the engagement of the belt or cord 43 with the pulley 44 the traveler will continue its rotation, and because of the engagement of the pin 49 with the worm 50 the said traveler will be caused to move from the position seen in dotted lines in Fig. 2 to the position seen in full lines in said figure and also in Fig. 4, it being remembered that the stud 16 is engaged by the dog 46, whereby the gears 8 and 9 are in mesh, and rotation is thus imparted to the feed-rolls. lVhen the traveler 41 has reached the position seen in Fig. 4, the engagement of the pin 42 with the'bent end 47 of the dog 46 will tilt the latter and so cause the notch 4S to be disengaged from the pin 16, and the spring 17 will move the stem 14 and the disks 11 and 13 and thereby one end of the shaft 10, so that the parts will assume the position seen in Fig. 3, at which period the gear 9 will be moved into the position seen dotted in Fig. 2, by reason of the eccentricity of the bearing of the shaft 10, so that said gear 9 will be out of mesh with the gear S and the rotation of the feed-rolls will be instantly stopped, whereby the attendant may be aware of the presence of au obstruction. Vtfhen it is desired to place the parts in operative position again, the stem 14 is moved upwardly in the direction of the arrow, Fig. 3, until the pin 16 can be engaged by the notch 4S in the dog 46 again, it being understood that when the licher-in roll 40 is properly r0- tating, the traveler 41 is in the position seen in dotted lines, Fig. 2, the engagement of the pin 49 of said traveler with the worm 50 causing said traveler to move outwardly into the position seen in Fig. 4, when the rotation of said lioker-in roll and worm ceases, the length of the pin 42 being such that it does not hit the portion 47 of the dog when the traveler is in its normalposition, (seen dotted in Fig. 2,) as is evident.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. An automatic stop attachment for a carding-machine, comprising a worm adapted to be secured on a continuation of the licker-in roll-shaft of the machine, a traveler on said worm, a shaft having gearing at one end, adapted to mesh with gearing on an operating-shaft of said machine, and having its other end mounted in a movable bearing, and mechanism intermediate of said traveler and movable bearing for operating the same, said parts being combined substantially as described.
